10 sats \ 3 replies \ @LibreHans 16 May \ on: Why Raising OP_RETURN Limits Helps Mitigate Spam bitcoin
So, a new place to add spam. It's a really simple question, do you think existing spam will move to that new place, or do you think that new spam will claim the new place, and that the old spam keeps using the old places? Will blocks be bigger or smaller because of this change?
If it becomes easier to broadcast transactions with larger OP_RETURN outputs, and more people do that, blocks become smaller. This is because each byte of OP_RETURN "costs" 4 vBytes, since it doesn't get the witness discount.
It's not clear that OP_RETURN outputs would take off in any meaningful way, but if we imagine a scenario where it totally did and blocks were chock full of only OP_RETURN data, those blocks would be 1MB large, and barely impact the UTXO set, while contributing a lot to fee pressure.

So in a world where we allow spam in witness data, spam in op_return might be less harmful. Sounds like we should allow less spam everywhere.
